Receding Chin Correction (Genioplasty)

Short Chin Lengthening and Advancement Surgery is a procedure that creates a defined, slender jawline from both the front and side by osteotomizing a short or recessed chin and lengthening it downward or advancing it forward. For a wide chin, the width is also reduced, and the surgical approach is determined by evaluating the chin shape with X-ray and CT scans.

Recommended for

· Those with a short chin · Those with a recessed chin and a flat side profile · Those with an asymmetrical chin

Chin Surgery Tailored to Your Chin Shape

Type 1. Short Chin – Chin Lengthening

The width of a wide chin is reduced, and the bone is moved downward to increase length, correcting a short chin and creating a slender, defined facial contour.

STEP 1. Customized Design

The amount of lengthening and width reduction is designed on the jawbone.

STEP 2. Osteotomy and Bone Repositioning

Rather than removing the cut bone, it is repositioned toward the lower chin to increase length.

STEP 3. Bone Fixation

The remaining bone segment is placed over and fixed to the adjacent bone to reduce width.

STEP 4. Jawline Contouring

The protruding side jawbone is smoothly contoured. During recovery, bone fills the empty space.

Type 2. Short Chin Tip – Chin Advancement

The chin tip is osteotomized horizontally and advanced forward, creating a more defined appearance from both the side and front.

AB Solution

For a slimmer facial shape from the front, it is recommended to combine chin surgery with Square Jaw Reduction. Various osteotomy techniques tailored to your chin shape and preferences create an attractive jawline.

Chin Reduction Only

This can result in an uneven, less smooth jawline.

Chin Reduction + Square Jaw Reduction

This creates a smooth, slender jawline.

Square Jaw Reduction Only

The effect on the front jawline is limited.

Square Jaw Reduction + Chin Reduction

This creates a slender jawline from both the front and side.

Combining Chin Reduction with Square Jaw Reduction creates a smooth jawline without secondary angles and a slender face that does not appear wide.

Strengths of AB Chin Surgery

Point 1. Meticulous Design Based on Nerve Pathway Location

The nerve pathway is identified with 3D-CT, and the osteotomy range is planned to avoid the nerve pathway before the procedure is performed.

Point 2. Smoothing Protruding Jawline Contours After Resection

Square Jaw Reduction smoothly contours the jawline for a natural transition without step-offs.

Point 3. Customized Design Considering the Entire Face

This customized procedure is tailored to the chin shape, adjusting the chin's length, position, and shape while considering overall facial balance.
